Chronometer?

Hi,

I am new to this forum.  I deal in vintage watches and have done so for some time.  I am about to purchase myself a watch as a gift from my wife and I really like the VC Overseas Dual Time.  Because of the kind of gift it is, I want a watch I can wear everyday for many years.  I like the robust style of the Overseas.  What I am wanting to know is if these watches are chronometer rated.  It isn't mentioned on the dial of the watch or in any info I have read.  If they don't come with a COSC Certificate, does it matter?  It'd certainly encourage me to buy one if it did.

I'd love to hear some opinions on the matter.

Cheers,

Damo.

Welcome to the Lounge Damo, the new Overseas models are not COSC

 rated, or no longer since 2004 when the new model was launched.

I personaly don't really care if the Overseas is COSC rated or not, its something which for me could be more important in a "dress" watch and in any event with modern materials used today all VC movements are quite accurate.

Hope thias helps

PS: your experience in vintage VCs can be an asset and hope to see you particpate here

chronometer. Its a great looking want from a premiere manufacture, its enough for me!

If it doesn't have a C.O.S.C. certificate,

it's best to assume that it will not perform within C.O.S.C. specifications. It will not necessarily be the case that it cannot (the JLC caliber 889 should be capable of it and I think IWC has had that movement certified successfully certified in the past), but it will be hard to get cooperation in regulating it.

I had an experience with one watch from a very reputable maker (not Vacheron) that returned from service keeping time reliably but running quite fast (well outside C.O.S.C. specifications). I was hoping that the company would regulate it for me, but they just told me it was "within specification." (A local watchmaker was happy to regulate it, of course.) Anyway, my point is that if it says C.O.S.C. on it, the manufacturer is more likely to take responsibility for getting it within +6/-4.
